Question

Please explain and help me on questions 1. 2. 3.

Answer 1

1. 203.976amu

2. 43.991amu

3. 334.36amu

Explanation:

Find a period table with the atomic mass units.

1 Hydrogen = 1.008amu

1 Carbon = 12.011amu

1 Oxygen =15.99amu

1 Nitrogen = 14.007amu

1 Sulfur = 32.066amu

Plugin for each equation

1. Sugar

6 C • 12.011amu = 72.066

12 H • 1.008amu = 12.096

6 O • 15.99amu =95.94

Add all together to get total amu (atomic mass units) for Sugar (6C12H6O)

95.94amu + 12.096 amu + 72.066amu = 203.976amu

2. Carbon Dioxide

1 C • 12.011amu = 12.011amu

2 O • 15.99amu = 31.98amu

12.011amu + 31.98 amu = 43.991amu

3. Penicillin

16 C • 12.011amu = 192.176amu

18 H • 1.008amu = 18.144amu

2 N • 14.007 = 28.014amu

4 O • 15.99amu = 63.96amu

1 S • 32.066 = 32.066amu

192.176amu+18.144amu+28.014amu+63.96amu+32.066amu = 334.36amu
